Letters .Patent No. 98,209, dated December 21, 1869.V

The Schedule referred to in these Letters .Patent and making part of thesame.

To Il whom itqnay concern l y Be it vknown that .Lf-ELISHA TURNER, of'Wolcottville, inthe county of Litchfield, 'and State ofConneeticlltflmve invented and made a new^ .and useful Invention inCord-'lightencrs for Curtain-llxtures; vand I do hereby declare thefollowing to be a full, clear, and exact description ofthe saidinvention.

' Cord-tighteners for cu|'tain'-pul|eys have before been made, with thepulley fitted in a slide having'rutehetxteeth, into-which a tongue orpawl upon .the pulleyblcck passes, -to hohlv the pulley to -any point atwhich it' niay be placed intighteninr the cord.

My invention consists in a slide, for the pulley, formed jitha seriesotholes through the thin sheetmetal of which the said slide is composed,the said slide'beingrased at the'hack part by means of ribs alonglheedges, in order that the project-ion upon the block of the pulley, inentering the said holes, may not come against the surface of'thewindow-casing t0 which the cord-tiglrtener may he applied.

In the drawingl Figure 1 is 11n-elevation of the said cord-tightener;

Figure 2 is a verticalsection ofthe same; and

Figure 3 is a horizontalfseetion at the line x x.

a represents the surface of. t'he window-casing or other place -ofattachment of the cord-'tightenexa bis thesheetmetal slide formed withthc returned edges-1 1-, between which the block c, carrying the pulleyd, slides.

The back ofthe slide?) is made with the ribs 2 2at the edges, so thatthe centre portieri of the slide at the hack is kept away from thesurface a, and in this centre portion ofthe back, holes, 3 3, areformed, and upon the block c is a projection, 4.

I When the' cord to the pulley is strained, the projection is `kept into one of the holes 3, the -bloelg c, rocking in 'its `slide by thestrain of said cord; but the projection '4, although passing through thehole, does not come into contaetwlth thesurfiiceor casing n. y rlhisconstruction allows the cortito he-slaekeued when-necessary,'as theblock -c can berocked to throw the projection 4 out of the hole What Iclaim, and desire' to secure by` Letters `Pat-A ent, is-

`The slide b, formed with the ribs 2 2, at the edges of the back, andthe holes 3 `3 in the raised portion of the'back, in con'ibinatio'nwith` the block c, pulley d, and prl'ijection 4as and for the purposesset forth.

Iii-Witness whereof, I have hereunto set myA signature, this Sth day ofOctober, A. D. 1869. L E. TURNER. Witnesses:
